Abstract
The invention provides a grinder comprising a grinding tank. A movable cover plate with a diameter similar to the inner diameter of the grinding tank is arranged on the bottom of the grinding tank. A material discharging port is arranged on the cover plate. A tank wall scraper is arranged on the edge of the cover plate. A rotary telescoping arm is connected to the center of the cover plate. A cylindrical grinding rod is arranged in the grinding tank. The grinding rod is driven by a driving shaft arranged on one end of a rod body. A gear is arranged on the driving shaft. The gear is engaged with a gear ring arranged on the port of the grinding tank. The driving shaft is connected to a driving motor fixed on one side of the gear ring through a universal spindle. The driving motor is electrically connected to a speed-adjusting circuit. The structure of the grinder provided by the invention is simple. The grinder has a small amount of pivoting pieces, such that abrasion is reduced. Also, when the speed is adjusted by the driving motor, different centrifugal forces are provided for the grinding rod, such that grinding pressure can be conveniently controlled immediately.
Description
Technical field
The present invention relates to the milling apparatus field, especially, is a kind of grinder.
Background technology
Grinder is that high-viscosity material the most effectively grinds, dispersing apparatus.Be mainly used in the grinding of liquid slurries such as various paint, printing ink, pigment, plastics, cosmetics, soap, pottery, rubber and plaster material.Making the viscose glue field, three-roll grinder is a kind of common equipment, the three-roll grinder operation principle: three-roll grinder reaches grinding effect through the surperficial mutual extrusion of three rollers of level and the friction of friction speed.Three-roll grinder is that high-viscosity material the most effectively grinds, dispersing apparatus.
Three-roller uses after half a year continuously, and an overhaul is carried out in suggestion, and the part of washing is is everywhere unpicked and washed, and changes clean lubricating oil again, and the unimpeded situation of scrutiny oil circuit, should in time repair when in unpicking and washing, pinpointing the problems.Find the roller distortion in use, must stop using, again reconditioning.Roller reconditioning number of times is too much, and roller diameter is less than after requiring, and can produce that travelling gear holds out against and roller leaves the phenomenon in slit each other, and this moment, gear must be revised.Simultaneously, three-roll grinder can not be adjusted the grinding dynamics through the gap of adjustment roller to the size of abrasive grains when grinding.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of grinder, this grinding machine structure is simple, fault-tolerance is high, does not need special maintenance, and its grinding pressure can conveniently be regulated simultaneously.。
The technical solution adopted for the present invention to solve the technical problems is:
This grinder comprises grinding drum, and said grinding drum bottom is the cover plate identical with the grinding drum internal diameter of an activity, and said cover plate is provided with discharging opening; Said side edge thereof is provided with a barrel wall scraper; Said cover plate center is connected with rotatable telescopic arm, is provided with the column grinding rod in the said grinding drum, and said grinding rod is by the drive shaft that is arranged on barred body one end; Said driving shaft is provided with gear; Said gear and the gear ring engagement that is provided with at the grinding bung, said driving shaft links to each other with the drive motors that is fixed on gear ring one side through universal drive shaft, and a said drive motors and an alignment circuit are electrically connected.
As preferably, said bucket wall scraper is a helical form, and said discharging opening is provided with barrel wall scraper and said cover plate junction.
As preferably, said grinding rod has the model of multiple diameter replaceable, and is different with the relative friction velocity of grinding drum bucket wall when the grinding rod of different-diameter grinds.
The invention has the advantages that:
1. adjust the speed of drive motors, grinding rod has different centrifugal forces, and promptly grinding pressure can be controlled easily immediately.
2. simple in structure, articulated part seldom reduces friction loss.
